Hey alan_lima

I didn't read your whole code, but I can tell you that you are using the wrong SPI settings.
Try exchanging the following part:

alan_lima:
SPI.begin();

SPI.setBitOrder(MSBFIRST);
SPI.setClockDivider(16);
SPI.setDataMode(SPI_MODE0);

delay(100);

with that:

//start the SPI library;
  SPI.begin();
  SPI.beginTransaction(SPISettings(1000000,MSBFIRST,SPI_MODE0)); //Set SPI to 1MHz, MSBFIRST and SPI_MODE0
